Note that every Google calendar has a 26 character source id. The calendar above has source (src): 3k405mddqiv6iq3g2at74kupd0. You can easily change the calendars by changing this source code for another calendars source code.

Also see that you can easily change the size and various other parameters of the calendar in the code.

It is also possible to import the calendar data and publish pages in your own format on your own webpage etc.However we advice to just use standard Google Calendars and embed this as this is easily reccognized and very stable.
